HG Series Single Cylinder Rotary Cylinder Drying
Machine, Continous Dryer with Internal Heating
Drum dryer is a kind of rotating continuous drying equipment with internal heating conducting-style. Certain thickness of materials film attach to the drum from material liquid vessel under the drum.
Heat is transferred to the internal wall of the cylinder through pipes and then to the external wall and to materials film, to evaporate the moisture film so as to dry materials.
Dried products are then scraped off by the blade fitted on the surface of the cylinder, fall down to the spiral conveyor under the blade, and conveyed, collected and packed.

Such processes as the HG series cylinder dryer is used in such trades as the food, chemical industry, medicine, etc. viscidity, lotion pastel supplies film-making, dry extensively.
1. High heat efficiency. The principle of heat transfer of the cylinder dryer is heat conduction and the conducting direction keeps identical in the whole operation circle. Except heat loss of end cover and radiation loss, all heat can be used for evaporation of wet materials on the wall the cylinder. The efficiency can reach 80-90%.
2. Large operation elasticity and wide application. Various drying factors of the dryer can be adjusted, such as concentration of feeding liquid/thickness of material film, temperature of heating medium, rotating speed of the drum etc. which can change drying speed of the under dryer. As these factors have no interrelations each other, it brings great convenience to dry operation and makes it applicable to dry various materials and to meet different requirement of production.
3. Short drying period. The drying period of materials is normally 10 to 300 seconds, so it is suitable for heat-sensitive materials. It also can be pressure reducing operated if it is put in vacuum vessel.
4. Fast drying rate. As film of materials coated on the wall of the cylinder is very thin. Normal, thickness is 0.3 to 1.5 mm, plus directions of heat and mass transmitting are identical, the evaporation strength on the surface of the film can be 20-70kg.H2O/ .h.
